The effects of static magnetic field and 50 Hz electromagnetic field on neuronal-like cells were investigated in the mid-infrared spectral region by means of FTIR spectroscopy in Fourier self-deconvolution.Exposure of 3 hours to a uniform magnetic field at the intensity of 2 mT produced a significant increase in intensity of CH2 methylene group vibration bands, which may be associated with an increase of lipid content related to an increase of the surface of the cellular membrane. In addition, a decrease of the PO2- phosphate bands was observed, suggesting that alteration in DNA/ RNA can be occurred after exposure. Further exposure up to 18 hours produced an increase of the β-sheet/α-helix ratio in amide I region due to unfolding processes of proteins.Exposure of 3 hours to a 50 Hz electromagnetic field at the magnetic flux density of 1 mT provided that signifycant increases of the amount of β-sheet content and of the band around 1740 cm−1 (assigned to non-hydrogenbonded ester carbonyl stretching mode) occurred after exposure, which may be considered as the main characteristic spectral signatures assumed as indicative of cells death.
